Just like rivals Samsung have opted for a non-Android platform, called Tizen, to succeed as the new OS for its Galaxy Gear wearables, HTC too have pitched in with its own platform for a smart watch which it plans to release at the upcoming Mobile World Congress in Barcelona this year.
According to speculations, the smart watch, called 'HTC Petra', will release alongside the much awaited HTC M9 and would be customizable.
The Petra will feature a 1.8-inch 32x160 POLED screenand come in different sizes. It would also support pairing with Android and iOS devices. This is the reason why the Petra will feature a non-android operating system - to support more platforms.

The in-built apps that should be present in Petra at the time of shipping will probably be containing controls for your other mobile devices, a timer, a stopwatch (seriously, a smart watch ought to support that), multimedia players, a calendar, an alarm, message and event notifiers, along with lifestyle and fitness apps to track fitness, eating habits and your lifestyle. The launch is hotly anticipated since the other specs and the price would be made public at the time of announcement.
We are not sure whether iPhone users will give it a chance with the Apple Watch just round the corner, but with the market flooding with Android Wear devices, it will be great to get something different for once.
